ABSTRACT Global carbon cycle is a very important issue in the study of global climate change. Forest ecosystem carbon cycle is one of the important part of global carbon cycle, but at the present time there are considerable uncertainties in the research of global carbon cycle, which also exist in forest ecosystems carbon cycle research, especially in the estimation of carbon storage of region forest ecosystems and CO〓 fluxes exchanging with other systems.

全球碳循环是全球气候变化研究的核心问题之一，森林生态系统碳循环是全球碳循环的重要组成部分，目前在全球碳循环的研究中还存在很大的不确定性，这种不确定性同样存在于森林生态系统碳循环的研究中，尤其表现在对区域森林生态系统碳库大小及其与大气CO〓交换通量的估计上。

It was discovered that when ethyl nitrite was introduced to the surface of catalyst, Pd ethoxyl compound was formed and simultaneously the active site Pd was transferred to the surface of catalysts with the change from Pd〓 to Pd〓. Then lined-adsorbed CO inserted into Pd alkoxyl compound to form the carboethoxypalladium complex.

研究结果表明，在CO偶联反应过程中，亚硝酸乙酯在催化剂上吸附，生成钯乙氧基络合物，同时将催化剂表面上的活性中心氧化，由Pd〓→Pd〓，并向催化剂表面上迁移。

欧 Paulicelli 讨论服装研究，她在 2008 年建立，现在 co-directs 在会议报告 107 Craduate 中心的城市新约克大学中跨学科的浓度。

The catalysts for the combustion of ethyl acetat ewer eprepared using Fe,Co,Cu,Cr,and Mn metal oxides as active components supported on Al2O3-Ce0.5Zr0.5O2 mixed oxides and characterized by X-ray diffraction,temperature programmed reduction,oxygen storage capacity measurement,BET surface area,XPS measurement,and activity test.

制备了Fe，Co，Cu，Cr和Mn金属氧化物催化剂，所用载体为Al2O3-Ce0.5Zr0.5O2复合氧化物。利用X射线衍射，程序升温还原，储氧量测试，BET比表面测试和光电子能谱表征了催化剂。并利用活性测试表征了各种催化剂对乙酸乙酯催化燃烧能力。

Phenol derived from two stage water gas gasification is produced in upward, and in downward, after tar, suspension and sediment removed, phenol, which has been filtrated, pressurized and atomized, is sprayed into regenerative chamber where phenol and high temperature lattice bricks exchange heat each other and phenol get into superheated vapor, then phenol come into gasifier with making up steam and in fire layer phenol is decomposed into H 2O and CO 2 which will go on reacting with blazing carbon and fo...

两段炉水煤气气化工艺在上吹制气阶段产生含酚冷却水，下吹制气阶段，将脱除焦油、悬浮物、沉淀物并进一步过滤后的酚水加压、雾化、喷入燃烧蓄热室内与高温格子砖进行热交换，使之汽化并过热，然后与补充过热下吹蒸汽一起进入气化炉火层，酚在高温作用下分解成H2O和CO2，并进一步与炽热的炭发生反应，形成H2和CO。

We find that the ferromagnetism of Ni nano-particles is significantly enhanced, and the magnetic interactions between Co particles are reduced, in the C〓 matrix.

发现C〓基质中的Ni纳米颗粒的矫顽力有显著增强，和Co颗粒间的磁相互作用减弱。

The results showed that CO gene was acquired from tall fescue and then designated as FaCONSTANS.

结果表明，从高羊茅中分离出CO基因，命名为FaCONSTANS。

The whole sintering process of SHS converter fettling materials can be divided into three steps. The first step is the decomposition reaction of carbonates and sodium nitrate, which is an endothermic reaction. The second step is the SHS reaction, i. e. thermite reaction, the metal of Al reacts with CO〓, O〓, NO〓, Fe〓O〓 to form Al〓O〓. The speed of thermite reaction is very quick, and accompanied with large amount of heat emission and temperature rise. The third step is the reaction of spinels formation. The Al〓O〓 produced by SHS reacts with MgO to form spinels.

整个SHS补炉料的烧结过程分三步进行：第一步为碳酸盐、硝酸钠的分解反应，属于吸热反应；第二步为SHS反应即铝热反应，金属铝粉与CO〓、O〓、NO〓、Fe〓O〓等反应生成Al〓O〓，反应速度很快，并伴随有巨大的放热和温度升高；第三步为合成尖晶石的反应，SHS反应产物Al〓O〓与MgO反应生成尖晶石。

The replacement of SF6 by refrigerant is under development. For example, R143a by AMC and FK by 3M Co. used as protection gas are both classified as HFC with short atmospheric lifetime and are easily to be decomposed into hydrofluoric acid, carbon monoxide and fluoric carbon monoxide at room temperature.

目前发展中的替代性保护气体以冷媒类为主，如澳洲AMC所采用的R134a及美国3M公司所开发的FK气体，两者都属於氟氢碳化合物，不过其半衰期短，即使在常温下，仍极易分解成氢氟酸、CO、COF2等，其中氢氟酸为有害物质，但因含量很少，且在高温下易与镁液反应，故对人体的为害很小。

A strong accumulation of Co〓, Ni〓, Cu〓, Zn〓 and Pb〓 by intact algae was observed. The algae killed by formol had comparable adsorbed ability to living ones.

藻体对Co〓、Ni〓、Cu〓、Zn〓、Pb〓有强的富积作用，用甲醛杀死的藻和活藻具有相似的吸附作用。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
